State highway in northeastern Illinois, US

Illinois Route 19 (abbreviated IL 19, or simply Illinois 19) is a major east–west arterial state highway in northeastern Illinois, United States. It runs from Illinois Route 25 (Liberty St.) in Elgin, to Lake Shore Drive (U. S. Route 41) on the north side of Chicago. Illinois 19 is 33.64 mile (54 km) long. In Elgin itself, it has since been renamed East Chicago Street. As of 2005, some signage on approaching streets still identified Irving Park Road as Chicago Elgin Road.

The original Route 19 was designated in 1918 as what is now U. S. Route 14 from Chicago Loop to Harvard. In 1935, the routing was removed, and in 1949 it was reapplied on part of its modern day routing. As of 1968, IL 72 was cut back from Lake Shore Drive (US 41) to its present terminus. As a result, the IL 19 designation was extended from its terminus at Narragansett Avenue (formerly assigned as part of IL 72) by 7 mile (11 km) to Lake Shore Drive in Chicago.

Irving Park Road once ran straight through where O'Hare International Airport's 04R/22L Runway now sits. The road was realigned to the south in the 1960s in order to build the runway. Again in 2012, the road was realigned to the south as part of the O'Hare Modernization Plan to build runway 10R/28L.

On November 16, 2006, aldermen in Wood Dale approved a plan to redesign the intersection of Irving Park Road and Wood Dale Road. The intersection is currently fully interconnected to railroad signals for the active Metra Milwaukee District/West Line tracks, creating a situation where vehicles on both roads may be at risk of being hit by oncoming commuter trains. In addition, freight trains emerge from the Canadian Pacific Railway's Bensenville freight railroad yard during off peak rush hours. After the $45 million reconstruction, Irving Park Road would have crossed underneath the railroad tracks further northwest from the current intersection. Two alternatives were advanced in a city council meeting: Alternate 2, which would move Irving Park Road slightly north, displace 18 businesses but have flood plain and line of sight issues, and Alternate 2A, which would displace 47 homes and 13 businesses. The plan was killed in early March 2007 after local opposition to a Division Street extension through property owned by Holy Ghost Church. The city has since decided to investigate alternative safety measures at the intersection, including the addition of turn lanes and red light cameras.
